Radial spherical plain bearings have an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated, or where oscillating or recurrent tilting or slewing movements must be permitted at relatively slow sliding speeds. EntrustBearing radial spherical plain bearings requiring maintenance have the sliding contact surface combination steel-on-steel. Bearings with this sliding contact surface combination require regular relubrication. The high wear resistance of the sliding surfaces makes these bearings especially suitable for bearing arrangements where heavy loads of alternating direction, shock loads or heavy static loads have to be accommodated. Bearings which have cylindrical extensions at both sides of the inner ring are intended for applications where normally spacer sleeves are arranged at either side of the bearing, or are specially designed for the bearing arrangements of hydraulic cylinders. spherical rod end, spherical rod ends. EntrustBearing maintenance-free spherical plain bearings incorporate special sliding layers of modern materials which have very low friction. The bearings can be operated without maintenance. They are used for applications where long bearing lives are required without maintenance, or where operating conditions are such (***** inadequate or total absence of lubrication) that the use of steel-on-steel bearing is inadvisable. The maintenance-free bearings are primarily intended for applications where loads are heavy and have a constant direction. They have only limited ability to take up alternating loads spherical rod end, spherical rod ends.
